The Bark Filter Processor is a 12 band fixed filter bank with individual outputs and envelope followers on each band as well as a voltage controlled mixer for blending the outputs. The filters are steep, 6th order bandpass filters with yellow LEDs indicating the level at the envelope followers’ outputs. The voltage controlled mixer has sliders and individual CV ins and draws the, “center”, “width” and “tilt” controls from the Harmonic Oscillator allow- ing the fixed filters to be scanned across blended and mixed in various ways, all at the same time. The even and odd filters can be patched in and out separately and one side’s followers can control the other side’s levels like a vocoder.
